A Leiningen plugin for setting (rewriting) the project.clj version according to a format specifier
Put [lein-version-spec "0.0.5] into the :plugins vector of your project.clj.
Add a :version-spec "0.1.~{:env/circle_build_num}" to your project.clj. Then run
$ lein version-spec
This will compute your new version number, and update your project.clj on disk to contain the new version
:version-spec uses the same syntax as clojure.core.strint/<<. namespaced keywords starting with :env, like ~{:env/foo_bar} will look for an environment variable named FOO_BAR. Function calling syntax can also be used ~(foo/bar). If your function isn't built into clojure.core, we recommend putting your code into a new lein plugin. See https://github.com/circleci/version-specs for an example.
lein-version-spec only uses apply for ~() function calls, so things like ~(if foo (bar)) won't work. If you need logic, put it in a plugin.
